5.1 FUNCTION
5.1.1 ONE TIME BINARY INPUT
It is possible to select frequency setting, torque limit setting or
position setting of one time data input by rotary switch CODE.
Figure 5.1.1shows data bit construction of one time binary input.
(Example of setting) In case of setting frequency to 60.0Hz by 0.1Hz
(Higher)
D15
D14
(1) Input value which 60 multiplies 10 to D15 - D0 terminal by 16 bits binary value.
D15
(1) 60 times10 = 600 ---- 0000001001011000 (Binary)
(2) When data input is definite, turn the strobe signal on.
(3) Turn the strobe signal off.
Precaution Refer to 5.3 "DATA INPUT TIMING" for signal input timing.
5.1.2 ONE TIME BCD INPUT
It is possible to select frequency setting, torque limit setting or position
setting of one time data input by rotary switch CODE.
Figure 5.1.2 shows data bit construction of one time BCD input.
(Example of setting) In case of setting frequency to 30.0Hz resolution by
0.01Hz
(1) Input value which 30 multiplies 100 to D15 to D0 terminal by BCD value.
30 times100 = 3000 ---- 0011000000000000 (binary)
(Higher)

(2) When data input is definite, turn the strobe signal on.
(3) Turn the strobe signal off.
